How to Do Frog Sit-up

  1. 1
    Setup

    Lie on your back with your knees bent and the soles of your feet pressed together, allowing your knees to fall open wide to the sides, forming a diamond shape with your legs.

  2. 2
    Setup

    Extend your arms straight overhead or cross them over your chest, ensuring your lower back maintains a neutral position against the floor.

  3. 3

    Exhale and engage your core, initiating the movement by lifting your head, shoulders, and upper back off the floor, bringing your chest towards your feet.

  4. 4

    Continue to curl your torso upwards until your shoulder blades are fully off the floor and your core is fully contracted, maintaining the frog leg position.

  5. 5

    Inhale as you slowly and controlledly lower your torso back down to the starting position, allowing your shoulder blades to gently touch the floor.

Tips

  • Focus on initiating the movement from your core, not by pulling with your neck or arms, to maximize abdominal engagement.
  • Maintain the 'frog' leg position throughout the entire movement; resist the urge to let your knees come together.
  • Control the descent phase, slowly lowering your torso back down to increase time under tension and enhance muscle activation.
  • Keep your gaze directed towards your knees or the ceiling to help maintain a neutral neck position and avoid strain.

Common Mistakes

  • ×Pulling on the neck instead of engaging the core can lead to neck strain; focus on keeping your chin slightly tucked and lifting with your abs.
  • ×Rushing the movement reduces effectiveness; perform each repetition slowly and with control, especially during the eccentric phase.
  • ×Lifting the lower back off the floor too early indicates hip flexor dominance; ensure your core is engaged to stabilize your pelvis and keep your lower back pressed down.
